The Rotary Torque System implemented by Broetje-Automation bolts two opposite bolts in parallel. The torque is absorbed by means of a torque support on the high-precision, electric screwdriving tools. The opposite arrangement ensures the tightening process (similar to a car tire) and the cycle time.
The positions are automatically approached and both fastening processes are controlled synchronously. Depending on the customer’s requirements, the existing technologies for digital factory integration at Broetje-Automation can be used. This starts with the planning of the processes and the layout and continues with simulation and offline programming based on digital twins. This trend will intensify in the future, as the reduced quality costs, especially in the case of large and complex components, are a major lever for increasing efficiency, avoiding errors and improving cost-effectiveness.
Broetje-Automation already incorporates sensor systems (e.g. laser, camera or radar guided) in numerous systems as well as the digital integration for simulation based on the Digital Twin, offline programming as well as inline quality assurance and documentation in order to be able to offer its customers a holistic solution to their production challenges. “For the future, we expect that even more technologies from our portfolio will be used,” Thomas Oetken dares to take a look ahead. In particular, the ever-larger rotor blades still hold a lot of potential. Broetje-Automation is already working on optimising the existing industrial lay-up technology for fibre composite structures for this area as well.
The transition to automated production in the wind power industry will not happen overnight. It requires a holistic approach to examine the upstream and downstream processes in order to use automation sensibly. “This will be a joint learning process between mechanical engineering and the wind power industry,” Oetken is convinced. “If we do it right, automation has the potential to stop the migration of production jobs abroad and bring more added value back to domestic regions.”
